SECTION 07620 - SHEET METAL FLASHING AND TRIM <br />PART 1 - GENERAL <br />1.1 RELATED DOCUMENTS <br />A. Drawings and general provisions of the Contract, including General and Supplementary Conditions and <br />Division 1 Specification Sections, apply to this Section. <br />1.2 SUMMARY <br />A. Section Includes: <br />1. Formed Products: <br />a. Formed steep -slope roof sheet metal fabrications. <br />B. Related Sections: <br />1. Division 7 Section "Sheet Metal Roofing" for custom -formed sheet metal flashing and trim <br />integral with sheet metal roofing. <br />1.3 PERFORMANCE REQUIREMENTS <br />A. General: Sheet metal flashing and trim assemblies as indicated shall withstand wind loads, structural <br />movement, thermally induced movement, and exposure to weather without failure due to defective <br />manufacture, fabrication, installation, or other defects in construction. Completed sheet metal flashing <br />and trim shall not rattle, leak, or loosen, and shall remain watertight. <br />B. Fabricate and .install roof edge flashing capable of resisting the following forces according to <br />recommendations in FMG Loss Prevention Data Sheet 149: <br />1. Wind Zone 1: For velocity pressures of 21 to 30 lbf/sq. ft. (1.00 to 1.44 kPa): 60-lbf/sq. ft. (2.87 - <br />kPa) perimeter uplift force, 90-lbf/sq. ft. (4.31 -kPa) comer uplift force, and 30-lbf/sq. ft. (1.44 - <br />kPa) outward force. <br />2. Wind Zone 2: For velocity pressures of 31 to 45 lbf/sq. ft. (1.48 to 2.15 kPa): 90-lbf/sq. ft. (4.31 - <br />kPa) perimeter uplift force, 120-lbf/sq. ft. (5.74 -kPa) corner uplift force, and 45-lbf/sq. ft. (2.15 - <br />kPa) outward force. <br />3. Wind Zone 3: For velocity pressures of 46 to 104 lbf/sq. ft. (2.20 to 4.98 kPa): 208-lbf/sq. ft. <br />(9.96 -kPa) perimeter uplift force, 312-lbf/sq. ft. (14.94 -kPa) comer uplift force, and 104-lbf/sq. ft. <br />(4.98 -kPa) outward force. <br />C. Thermal Movements: Provide sheet metal flashing and trim that allows for thermal movements from <br />ambient and surface temperature changes. <br />1. Temperature Change (Range): 120 deg F (67 deg C), ambient; 180 deg F (100 deg C), material <br />r surfaces. <br />L <br />Wabasso Beach Park 07620-1 <br />Indian River County <br />DAA Project No. 6008 <br />
